Measure
Split-body 1% Sirolimus Cream (TD201 1%)
This is a split-body design. Subjects will self-administer 1% topical sirolimus cream or placebo cream (no drug, vehicle control) on the plantar surface of each foot. At least one foot will be treated with topical sirolimus at some time during the study. Application will be one time daily for a total of 26 weeks. There will be an additional follow-up visit 3 months after the last application of study drug. The total duration of the study is 39 weeks. 1% sirolimus cream (TD201 1%): 1% sirolimus cream (TD201 1%)

PRIMARY outcome

Timeframe: Two weeks and every 1-2 months for 24 weeks or within 2 weeks after the last dose of study drug

Population: Starting at week 13, visit 4, there were only 14 participants with available data.

The primary outcome measure for this Phase 1b safety study is evaluation of system absorption through measurement of serum sirolimus trough levels. The limit of detection of the assay was 2.0 ng/mL.

Timeframe: Prior to application of study drug and within 15-45 minutes after application of study drug at each visit for 39 weeks

Investigator assessment of local tolerability at the application sites on the plantar surfaces will be evaluated by the Investigator according to a 4-point scale (0, 1, 2, or 3; none to severe) with regard to: erythema, pruritis, stinging/burning, and crusting/erosion

OTHER_PRE_SPECIFIED outcome

Timeframe: Each study visit over 39 weeks

An expert in the disease who is blinded to the study treatment will read the photographs of the callus area taken at each study visit. The reader will assess changes to the calluses based on criteria such as blisters, cracks, small/large size, and red or bloody spots on the callus. Change in calluses will be reported for both the right and left foot.
